Erm... If the app keeps track of drivers journeys
And my point is there is no way to reach objective consensus on the driver's journeys. Read my prior post again and try to understand it, because it flew right over your head.
You n00bs don't even have a fucking clue at all about the technology.
Consensus is not needed, just details of the journey and rate. As an astute, brilliant and seasoned developer I would have assumed you knew that.
